I just wanted to show some tools that are helpful for GameBoy repairs:
Today I decided to build something helping me to decide stuff. So I decided to build an electronic dice with an included YES/NO-answering machine.
Below is the schematics (CC5 source code on request):
As you can see on the photo of the eDice I used two different colors for the LEDs. When pressing the YES/NO-button either the green (YES) or the yellow (NO) LEDs light up.
When used as a dice one to six LEDs show you the value of your dice roll.
I had no battery holder therefore I built one using some wires and lots of solder…
